PLC control of power supply system

For more than 10KW of electricity display, should be equipped with power distribution cabinet. According to the need to have a choice between using the remote control or with a PLC control of the distribution cabinet, with PLC control of the distribution cabinet smarter, LCD controller can be used long-range operation with LED display screen and air-conditioning, fans, and other equipment switch , On the screen within the ambient temperature, fire, the environment outside the screen brightness to carry out real-time monitoring, and the corresponding warning message. The external color display room in the proposed project, due to the generally poor environment, as far as possible with the use of PLC control of the distribution cabinet; indoors screen projects, a better environment, and space is limited, can not control the PLC.


Long-range communications

When the communication distance of 1.2 kilometers, the lines of communication can be installed in a pair of RS422/RS232 communications module; if the communication distance of several kilometers and even a few dozen kilometers, at this time should be used fiber-optic communications, PLC and computer communications both ends of the module is also Should be replaced by fiber-optic RS232 converter.

Power monitoring

To reduce the high-power start-up screen on the impact of the power grid, power display a few hours delay on electricity, PLC control interface on the failure of the police state of the power supply box are various power-on state of alarm indicator light.

Temperature monitoring

LCD monitor controller interface can display in real-time temperature display. Automatic mode, when the body temperature of more than 65 screen, the screen will be prompted to monitor the temperature is too high, LCD controller at the same time issued a warning sound, the system will automatically power to prevent a fire.

Fire Monitoring

Ping is also equipped with a number of smoke detectors, when the screen there when the fire occurred, LCD monitor controller interface will also have a corresponding message at the same time the system will automatically power.
